Action Required: Elimination of Single-DES SupportSCS Computing Facilities is making changes to the Kerberos environment on Monday, August 12, 2013. This change requires all users to change their SCS Kerberos passwords. You DO NOT need to change your SCS Windows password.
SCS Kerberos passwords are used for authenticating to a number of services, including:
- WebISO (including Webmail)
- IMAP email accounts
- SCS accounts on Linux machines
- SCS VPN
SCS Kerberos passwords can be changed using the Instance Manager at:htps://webiso.cs.cmu.edu/instance
If you are not sure if you still need to change your SCS Kerberos passwords, you can log in to the Instance Manager to check. Any instance highlighted in yellow will need to have its password changed.
Until you change your main Kerberos password, the following warning will appear when you log in to the Instance Manager:
Warning: Your main SCS user account has only a single-DES key and therefore will stop working after August 12, 2013. To correct this issue, change your password using the Change Password link above before that date.
For more details about the Kerberos change that requires these password changes, please see the following URL: http://www.cs.cmu.edu/~help/news/archives/elimination-single-des-support.htm l
Note: Kerberos passwords can be changed from an SCS Linux machine using the kpasswd command.
Please contact the SCS Help Desk at x8-4231 or send email to firstname.lastname@example.org if you have any questions regarding this service change.
